CAR FOR COKE.

SPECIFICATION forming part of Letters -Patent No. 425,797, dated April 15, 1890.

Application filed January Z4, 1890. Serial No.33'7,964. (No model.)

To all whoml it may concern:

-Be it known that I, CHARLES W. HUNT, a citizen of Jthe United States, residing at West New Brighton, in the county of Richmond and State of New York, have invented an Improvement in Cars for Coke, of which the following is a specification.

In the manufacture of gas from bituminous coal the coke is usually raked out from the ret-Ort into a car, in which it is conveyed to the place of delivery and the incandescentcoke 1s extinguished and cooled by the action of water, and in the manufacture of coke in the ordinary coking-furnace cars of a somewhat similar construction have been made use of for receiving such coke; but in consequence of the high heat of the coke when it is brought into contact with the car the sheetiron of which the car is composed is rapidly burned out, and considerable cost is involved in lthe renewal of such cars.

My present invention relates to the combination with the sheet-iron car-body of waterpipes permanently connected with such carbody and perforated and arranged in such a manner that when the supply of water is introduced into such pipes the water issues upon the interior surfaces of the sheet-iron of the car, thereby forming a cooling and protecting stratum of water between the hot coke and the car.

In the drawingl have represented by a vertical section a coke-car with my improvement applied thereto.

The shape, size, and character of the cokecar may vary according to the place'whereit is to be used and the quantity of coke which 1s to be received. I have represented in the drawing a car as made with sheet or plate iron ends A A, sides 1S, and double inclined bottoms C C, and this car is to be supported upon any suitable frame and provided with wheels, as illustrated in the drawing. Around the upper part of the car there is a pipe D, secured in position and perforated on its under side adjacent to the surface of the end and side platesA li, and there may also be perforationsdirected inwardly for the passage of water into the coke, as shown at 3.v There is a transverse pipe E at theapex' of the inclines C C/,whieh pipe is also perforated upon its under surface, and it is connected to the pipe D by a suitable branch or connection F.

From t-he pipe D a branch or connection G passes outwardly and i-t is provided with a coupling, so that a hose or other supply-pipe H may be connected to this pipe G, in order that Water may be introduced into the pipes D E F, either before the incandescent coke isv dumped into the car or immediately thereafter, in order that the interior surface of the sheet or plate iron car may be kept cool and moistened by the stratum of water running over the same from the perforations in the pipes D and E. The water which is supplied into ,the car also tends to extinguish the coke, either bythe steam formed from the water as it runs over the surface of the iron, or by the jets of water directed upon the coke within the car, or both, thus not only facilitating the extinguishing of the incandescent coke, but effectually lpreventing injury .to the iron car.

This car is adapted to the transportation of other hot or incandescent materials be' sides coke, but with some kinds vof roasted ores and mineral substances the direct contact of water therewith is detrimental.

I claim as my invention-'- The combination, with the iron car for coke or similar incandescent or hot materials, of perforated pipes around the interior of such car near the upper part thereof, and couplingconnections for a water-supply, whereby the metallic car is protected from injury by a stratum of water caused to pass over its interior surface, substantially' asset forth.

Signed by me this 2d day of January, 1890.
